Prostate Home > Jalyn

Men who have an enlarged prostate (also known as BPH) may benefit from Jalyn. This prescription medication contains two BPH medications and works to relieve symptoms by shrinking an enlarged prostate and relaxing the muscles of the prostate. The drug is available in capsule form, and is taken only once a day. Potential side effects include dizziness, impotence, and a decreased sex drive.

What Is Jalyn?

Jalyn™ (dutasteride/tamsulosin) is a combination prescription medication licensed to treat an enlarged prostate (also known medically as benign prostatic hyperplasia, benign prostatic hypertrophy, or BPH). Jalyn contains two BPH medicines -- dutasteride (Avodart®) and tamsulosin (Flomax®).

Who Makes This Medication?

Jalyn is jointly manufactured by Catalent Pharma Solutions and Rottendorf Pharma. It is distributed by GlaxoSmithKline.

How Does Jalyn Work?

Dutasteride, one of the active components of Jalyn, is a 5-alpha reductase inhibitor. It works by blocking the conversion of testosterone into dihydrotestosterone (DHT). This decreases the amount of DHT in the body. Because DHT is responsible for enlarging the prostate, using Jalyn to reduce DHT levels can help shrink an enlarged prostate and relieve symptoms of the condition.
Tamsulosin, the other component, belongs to a class of drugs called alpha blockers. It works by blocking alpha-1 receptors. These receptors are found in several places of the body, including the prostate gland. Blocking alpha-1 receptors in the prostate gland helps to relax the muscles of the prostate and the bladder neck (where urine leaves the bladder), helping to relieve enlarged prostate symptoms.
